The Food and Drug Administration warns customers to look out for salmonella symptoms including diarrhea, fever, abdominal cramps and vomiting. Symptoms are likely to arise within six to 48 hours of consumption, according to the FDA.

Illness could last between four and seven days and is typically resolved without treatment other than drinking a lot of fluids. However, in the case of severe diarrhea, hospitalization would be required, according to the agency.

Frequent hand-washing is cited by the FDA as the best way to avoid contracting salmonella.

Goldfish is just the latest in salmonella-related recalls. Kellogg's Honey Smacks cereal was recalled because of a salmonella outbreak in June.
